The man in front of him had black hair, black eyes, and deep pupils, and did not have any of the symbolic characteristics of an evil spirit.

But the blood ghost technique just now was not an illusion...

An unbelievable thought arose in Butterfly Ninja's heart, followed by a despair that nearly suffocated her.

"You are... Kibutsuji Muzan!"

The leader of all demons, the legendary king of demons, and the ultimate goal of the Demon Slayer Squad - Muzan Onimushuji!

Only the Ghost King, who is superior to all evil ghosts, can have such terrifying and powerful strength!

Cui Ze black-bone chicken and mackerel.

"Who are you calling a scumbag?!"

Butterfly Ninja is not a dull, natural idiot like Tomioka Giyu who can't read the atmosphere.

At least, she could see Cui Ze's unhappiness and speechlessness.

That feeling...

It's like calling the other party Kibutsuji Muzan...

It's like the ultimate humiliation...

'Who...is this guy?'

The suspicion and suspicion in Butterfly Ren's heart gradually dissipated, replaced by a touch of curiosity, and he truthfully expressed his feelings.

"I'm just a casual traveler."

Cui Ze saw that the atmosphere between them was not as hostile as before, so he removed the restraints on Butterfly Ninja.

He was really worried about conflict with each other.

After all, Cui Ze hasn't faced an E-level enemy for a long time.

If you are not careful, you may crush the butterfly ninja to death like a bug...

Ahem.

Cui Ze recalled the first time he went fishing, the [Breath of the Beast] that had been of great help on Kamen Island (Zombie Island), and said lightly.

"Based on my past experience, I will provide a certain degree of help to the Demon Slayer Corps' ghost-killing plan."

"help……"

Butterfly frowned imperceptibly.

After the test just now, she fully recognized the other party's strength, but in the final analysis, the other party was too mysterious.

Mysterious and difficult for people to approach or trust.

"This, sir."

Butterfly Ninja easily changed her words, and the formulaic smile appeared on her cheeks again.

"If you are willing to join the Demon Slayer Corps, I can introduce you to the Lord of the Demon Slayer Corps!"

"Let's forget it, miss."

Cui Ze sneered.

“Japan in the Taisho Era…

"If I really stay here for a long time, I'm still a little worried that I won't be able to help myself and sink the Japanese archipelago!"

This time, he was speechless. It was Butterfly's turn to endure.

She could feel that the other party was not joking.

And what's even weirder is...

The other party's arrogance and confidence from the bottom of his heart when he talked about the "Sunken Islands"!

This man's strength is absolutely unimaginable!

Butterfly Ninja adjusted his mood.

"Sir, what do you mean by 'help' just now?"

"I have learned a skill before, called [Breath of the Beast], well, it can be regarded as a branch of [Breath of the Sun] - no, [Breath of the Wind]."

【Breath of the Sun】?

Butterfly endured his gaze.

What is that?

[Breath of Wind] sounds familiar.

But what is [Breath of the Beast]?

Which Demon Slayer member created his own breathing style?

Cui Ze's words continued, and the butterfly ninja had no choice but to suppress the curiosity in his heart.

"[Beast Breath] has given me a lot of help. Considering this relationship, I plan to share a new breathing method with the Demon Slayer Squad, called [Ripple Qigong]."

"[Ripple Qigong]?"
